Information on CVSS is documented in HPE Customer Notice: HPSN-2008-002

RESOLUTION

HPE has provided RTMS v3.0.50 or subsequent to resolve this issue.

HPE has also provided a mitigation to defend against the risk, until the update
is applied by customers. The problem is addressed in the latest version of RTMS
(3.0.50) due in October 2018.

  o Resolution - Customers should upgrade to RTMS 3.0.50 to obtain the fix in
    the code which discards zip files containing invalid and/or malicious
    paths.

  o Note: If the ability to upload zip archives has been disabled using the
    commands in step [1] below, then this ability must be re-enabled using the
    commands in step [2] above before performing the upgrade.

Interim Product Modification (IPM)s -

Recommended Actions:

  o It is recommended that the customer not use the "Upload MIB Archive"
    facility on unknown archive files to mitigate this risk. The following
    steps can be used to disable the feature.

      - [1] For existing installations, the ability to upload zip archives can
        be disabled by using the following commands on the RTMS Server (or on
        both the Primary and Secondary server for an HA installation):

(as root)

mkdir -p /opt/OC/rtms/conf/mib
chown rtmsadmin:rtmadmin /opt/OC/rtms/conf/mib
chmod ugo-wx /opt/OC/rtms/conf/mib

  o [2] The ability to upload zip archives can be restored by allowing write
    permission to the mib folder again: chmod ug+wx /opt/OC/rtms/conf/mib All
    zip archives should be manually unzipped and inspected on a desktop before
    being uploaded on an RTMS server if this facility is needed.

Interim Product Modification (IPM)s -

  o All existing releases of RTMS are affected by this error.
